PRC PRC Exercise Prescription & Home Program Design 1 — Questions and Answers
Question 1: When designing a PRI home exercise program, which factor is MOST important for initial exercise selection?
- The patient's overall fitness level and baseline strength
- The patient's ability to feel and reproduce the target position or pattern (Correct answer)
- Maximizing the number of exercises to address all patterns efficiently
- Selecting exercises that simultaneously address all identified patterns
Correct answer: The patient's ability to feel and reproduce the target position or pattern
In PRI, the patient's ability to sense and reproduce the target repositioned position is prioritized because sensory awareness drives the neuromotor repatterning process.
Question 2: How many exercises are typically recommended in an initial PRI home program?
- 8–10 exercises performed twice daily for maximum stimulus
- 1–3 exercises performed correctly with attention to sensory goals (Correct answer)
- A full-body circuit of 12 exercises targeting all chains
- 5–7 exercises performed once weekly to prevent overtraining
Correct answer: 1–3 exercises performed correctly with attention to sensory goals
PRI home programs typically start with only 1–3 exercises to ensure quality of performance, sensory awareness, and patient compliance rather than volume.
Question 3: In a PRI home exercise session, inhibitory techniques are used to:
- Fatigue the target muscle to prevent overuse injury
- Reduce neural drive to overactive muscles before facilitating inhibited antagonists (Correct answer)
- Restrict range of motion during resistance exercises
- Assess baseline strength of antagonist muscles before training
Correct answer: Reduce neural drive to overactive muscles before facilitating inhibited antagonists
PRI inhibitory techniques reduce neural drive to overactive muscles, creating the neuromotor relaxation needed to then successfully facilitate activation of the inhibited antagonists.
Question 4: When prescribing PRI exercises that include nasal breathing and exhale holds, the primary purpose is to:
- Increase tidal volume to support aerobic conditioning demands
- Facilitate diaphragm repositioning and improve the zone of apposition (Correct answer)
- Reduce heart rate as a relaxation response during exercise
- Prevent a Valsalva maneuver during loaded movements
Correct answer: Facilitate diaphragm repositioning and improve the zone of apposition
Nasal breathing with exhale holds in PRI facilitates diaphragm repositioning and improves the zone of apposition, restoring proper thoracic mechanics and trunk pressurization.
Question 5: Which of the following BEST describes the key principle for progression in a PRI exercise program?
- Increase external resistance weekly regardless of current movement quality
- Progress only when the patient consistently achieves and feels the target position (Correct answer)
- Always add at least one new exercise per treatment session
- Progress from bilateral to unilateral exercises as the first progression step in all patterns
Correct answer: Progress only when the patient consistently achieves and feels the target position
PRI progression is based on the patient's consistent ability to achieve and proprioceptively sense the target position, ensuring neuromotor learning is occurring before increasing challenge.
Question 6: A patient reports performing PRI exercises but cannot feel the intended muscle activation. The BEST next step is to:
- Increase repetitions and sets to intensify the stimulus
- Replace the exercise with a different one without reassessing
- Reassess positioning and add tactile or verbal cueing to improve proprioceptive awareness (Correct answer)
- Order imaging to rule out structural pathology preventing activation
Correct answer: Reassess positioning and add tactile or verbal cueing to improve proprioceptive awareness
When PRI sensory goals are not being met, reassessing positioning and adding tactile or verbal cues helps develop the proprioceptive awareness needed for successful repositioning.
